Is the C6 worth the extra over the C5?

Only if the gap is small. The C6 adds a brighter evo panel, the a11 Gen3 chip and 165Hz VRR. At $1,399.99 as of November 3, 2026, it is $450 over its own $949.99 low, so wait for a drop or take the C5 if it is much cheaper.

Which is better for gaming?

The C6. It runs VRR up to 165Hz with G-Sync and FreeSync Premium and a 0.1ms response. The C5 is still strong with 4K 120Hz, ALLM and QMS on all four HDMI 2.1 ports.

Which has the better picture?

Both use self-lit OLED pixels with perfect blacks and Dolby Vision. The C6's Brightness Booster and newer processor give it an edge in bright rooms and with upscaling; the C5 is close in a dark room.

Do both support Dolby Vision and Dolby Atmos?

Yes. Both handle Dolby Vision, HDR10 and HLG, and both decode Dolby Atmos. The C5 lists 40W 2.2-channel speakers; a soundbar still helps either set.

Neither has a published lifespan edge. Both are OLED, so avoid leaving static logos or tickers on for hours. The C5 has more owner history at 2,339 ratings; the C6 is too new for long-term reports.

What sizes do they come in?

The C6 line runs from 42 to 83 inches. The C5 specs here list a 55-inch set; LG sells the C5 in several sizes, so check the size you want before comparing prices.
